Title: Improvements in or relating to the manufacture of hydrogen peroxide
Inventor: BEARD JOHN STEWART
IPC: C01B15/023
Filed: 1956-09-20
Abstract: Hydrogen peroxide is made by hydrogenating a salt of an anthraquinone sulphonic acid in aqueous solution in the presence of a hydrogenation catalyst and oxidizing the reduced compound formed with oxygen, so as to regenerate the original salt and produce hydrogen peroxide, which is separated.  The preferred salt is the sodium salt of anthraquinone-2 : 7-disulphonic acid.  A suitable catalyst is palladium supported on silica gel, carbon, or synthetic zeolite; the catalyst may be prepared by impregnating silica gel with sodium chlorpalladite, igniting at 650 DEG  C. and reducing with sodium formate.  For a continuous hydrogen-peroxide production process, a column of granular catalyst may be used, through which the solution and gaseous hydrogen are passed in co- or counter-current; the reduced solution is filtered and oxidized with air free from carbon dioxide in the presence of excess slaked lime slurry; calcium peroxide is precipitated and may be filtered off, decomposed with carbon dioxide, and the hydrogen peroxide solution concentrated, after passing, if desired, through anion and cation exchange resins to remove impurities.  Alternatively hydrogen is bubbled through a suspension of finely-divided catalyst in the solution in a reaction tube; the mixture is agitated in the lower part of the tube and allowed to settle in the upper part of the tube which is provided with gauze funnels; the hydrogen peroxide is obtained from the reduced solution as in the column process.  Suitable apparatus is described with reference to drawings.

Title: Improvements in audible and visual signals as used for mining shaft signals and the like
IPC: B66B19/06
Filed: 1919-11-26
Abstract: 139,136. Vicary, W. O. Nov. 26, 1919. Mechanical telegraphs.-In apparatus for mine- and like signalling, three members M<1>, M<2>, M<3> are provided, adapted to slide on vertical guides N, and each has a ratchet and retaining pawl P<1>. P<2>, P<3>. Normally, these members rest on one another as shown, and signalling-impulses, either electric or mechanical, are applied to a rod S and operate a link L having a pawl P<4> which serves to raise the member M<1> step by step, carrying the members M<2>, M<3> with it. Member M<3> carries a contact C<3> adapted to engage a fixed contact when three impulses have been given, preparing .the circuit of a cautionary signal lamp in the indicator (not shown). Member M<2> carries a contact C<2> which traverses a row of contacts C' corresponding with successive impulses, and connected individually to corresponding lamps in the indicator. Member M<1> carries contacts C<1> which are held open when the member M<2> rests on the member M<1>. A spring contact C<7> is also provided which is held in contact with a fixed contact C<9> when the member M<1> is in its lowest position, but engages a contact C<8> when the member M<1> is raised. Contact C<9> is in a common return lead from the indicator lamps, so that the circuits prepared by contacts C<2>, C<3> are not completed to light the lamps unless contacts C<7>, C<9> are closed. Contact C<8> is in series with a release magnet R<1>. When a signal has been completed, and after a period controlled by a dash-pot D, a contact C@ (which has been opened bv the upward movements of red S) closes and completes a circuit through release magnet R<1>, allowing member M<1> to fall, thus closing the contacts C<7>, C<9>. The members M<2>, M<3> are maintained raised. When the first impulse of a succeeding signal is given, contacts C<5> in series with contact C<1> and a release magnet R<2> are closed, and the member M<2> falls upon member M<1> and registers the new signal impulses. When a signal is compiled with, an engine-controlled contact (not shown) closes the circuits of release magnets R<2>, R<3>, so that both members M<2>, M<3> fall, and the signal is cancelled. Convacts C<5> also control the circuit of a bell (not shown), so that an audible signal is given on each signal impulse.

Title: Improvements in and relating to electric discharge devices
IPC: H05B41/19
Filed: 1932-10-24
Abstract: 406,413. Discharge apparatus. BRITISH THOMSON-HOUSTON CO., Ltd., Crown House, Aldwych, London.-(Assignees of Buttolph, L. J. ; 1, Columbia Avenue, Grantwood, New Jersey, U.S.A.) Oct. 24, 1932, No. 29717. Convention date, Oct. 24, 1931. [Class 39 (i).] A discharge device, such as a lamp or a rectifier, the operating potential of which is insufficient to initiate the discharge, is started by the application of a high potential, which is obtained by interrupting the passage through an inductance of a current fed from a unidirectional source, the potential of which is lower than that used for maintaining the discharge. The potential, preferably, is less than the ionizing potential of mercury in order to avoid arcing in the mercury switch connected in the inductance circuit. The source of low potential may be obtained from an alternating-current supply through a double or a half-wave oxide rectifier, from a battery, or from a potentiometer connected across a direct-current supply. A double-wave rectifier 10, Fig. 1, is connected to tappings on the supply autotransformer 5, and a mercury switch 9 is adapted to break the current through an inductance 7 to impose a high potential upon an external electrode 4. The rectifier may be connected to the supply transformer through an autotransformer 11, Fig. 3. Two separate half-wave rectifiers 10<1>, Fig. 4, may be connected to a switch 9<1>, Fig. 4, provided with three contacts as shown. In a modification, one inductance 7<1>, Fig. 7, is connected in series with the device for normal operation and another inductance 7<11> is used in the ignition circuit. The magnitude of the condenser 13 is such that it will pass the high potential current but will not pass the normal discharge current. The inductances may consist of two or of tapped windings on the same core or of windings on separate cores, in which case the switch is adapted to be operated by either inductance through separate armatures. In a lamp 21, Fig. 8, having an indirectly-heated cathode 22, starting is delayed by a thermostat 28 which is heated by a resistance 27 connected in the inductance circuit to short-circuit the said resistance. The low-potential source may be obtained from a potentiometer 17, Fig. 12. A switch 9 in series with the inductance and a hydrogen-filled switch 16, which is adapted to disconnect the potentiometer from the mains upon ignition, are actuated by the inductance through one armature.

Filed: 1972-06-24
Abstract: 1424326 Counters LUCAS ELECTRICAL CO Ltd 15 June 1973 [24 June 1972] 29720/72 Heading G4D  A counter has a plurality of numeral rollers 18-21 loosely mounted on the shaft 17 of a reset knob 15 between frictional driving discs 22-26, multiple detents 29, 30 being arranged such that transfer is effected between rollers to count as the shaft 17 is turned in one direction and all rollers are returned rapidly to zero if it is turned in the other direction. The counter is for registering " distance " on an exercise bicycle. An input drive 14 is coupled to the first friction disc 26 by a loose gear 50 eccentrically mounted on a shaft 16 and having two sets 51, 52 of different numbers of gear teeth. One set of teeth 51 co-operates with teeth on the disc 26 while the other co-operates with a toothed member 28 held stationary by ratchet teeth 53, 54. All the rollers 18-21 and discs 22-26 are clamped by a spring 27 so the drive is imparted to all the numeral rollers. Only the first 21, however, is free to turn continuously, the others being held by abutments 41, 42, 43 of a first spring blade assembly 29. Each roller 18-21 has small lugs 32 projecting between the numerals and a single long lug 33, being a continuation of one small lug. The abutments 41, 42, 43 face and engage the small lugs. Oppositely facing abutments 46-48 on a second spring blade assembly 30 are aligned with the long lugs 33. Wehn the counter is driven forwards, as roller 21 completes a revolution its long lug 33 sweeps aside the abutment 48 which also displaces the aligned blade 40 of abutment 43 so that the next highest roller is free to turn through one step and so on. When the shaft 17 is reversed by knob 15 all rollers are frictionally driven backwards until their long lugs 33 strike the detents 45, 46, 48, in the zero position. The member 21 jumps over the ratchet teeth to permit the resetting movement independently of the drive 14.
